采用气相金属化法制备了NbC/C/NbC ~ NbC复合微线圈和微管，并对其制备条件和性能进行了研究。碳线圈从表面到核心被铌化，并保留了卷曲形态，形成NbC/C/NbC ~ NbC复合微线圈或微管。根据铌化率和堆积密度的不同，其体积电阻率和比表面积分别为0.3 ~ 0.02 Ω·cm和2 ~ 18 m2/g。
NbC/C/NbC∼NbC composite microcoils and microtubes were prepared by vapor phase metallizing of regular carbon microcoils, and the preparation conditions and some properties were examined. The carbon coils were niobilized from the surface to the core with preservation of the coiling morphology to form NbC/C/NbC∼NbC composite microcoils or microtubes. The bulk electrical resistivity and specific surface area were 0.3 to 0.02 Ω·cm and 2 to 18 m2/g, respectively, depending on the niobilized ratio and the bulk density.
